The cdns3 host role does not care about reset-on-resume. xHCI however
reconfigures itself in silence rather than printing a warning about a
resume error. Related warning example:

  [   16.017462] xhci-hcd xhci-hcd.1.auto: xHC error in resume, USBSTS 0x401, Reinit

Allow passing a CDNS3_RESET_ON_RESUME quirk flag from cdns3 pdata down
to xHCI pdata. The goal is to allow signaling about reset-on-resume
behavior from platform wrapper drivers.

When used, remote wakeup is not expected to work.
